Here's what we did in Apache (httpd.conf)
<IfModule alias_module> ... Alias /share "//myhost/myshare" </IfModule>
<Directory "//myhost/myshare"> Options Indexes MultiViews AllowOverride None Order allow,deny Allow from all
</Directory>
Now we can access the share drive via HTTP from http://wikihost/share. It works in all browsers: no need for file: links.
That only works if all the files are readable by apache; at which point you've just subverted your file system protections. This works fine if the data is already accesible by everyone, but not so well if the files have limited access.
V/r,
